Yes - you need to connect the 5V line to the 9V line and remove the
regulator.
You won't connect the 5v regulator socket in/out on the QL as suggested
in the Qplane manual (8-)#
Hehe as I can clearly see from the copy I don't have :-)
This method is _very_ bad as it makes the power line inordinately long.
Work out which the 9V line is on the expansion connector (continuity
meter to power pin nearest network.
There's also a thick cable (which was probably connected by the previous owner (BTW: Serial No: S13-002319)
that runs from 1 mm right of the C5 (next to the ROM port) next to pin 13 (counting from top left) of the 68008 (which has pins 15 (left side) connected to pin 14 (right side) via a solid line and that line being connected through a ceramic capacitor to pin 13 (left side).
Also that little board I was talking about has two resistors, a capacitor and a M74HCU00481 (98423) IC and it is connected via 4 cables to positions right above IC1 and IC2 and on DC19 and DC22).
Overall (it's been awhile since I had a real QL in my hands so from what I remember) it weighs almost twice as much as a European QL..... (So apparently it can be used instead of a baseball bat :-)
Ditto 5v on the motherboard - the 9V line is the top connector near the
back of QL, and there is a convenient 5V pad on the motherboard.
.... and connect them with a good thick wire.
Jumper all expansion 5v regulators, and that is it.
...bar putting a large sign on everything saying 5V only.
Speaking from experience, SGC will survive a few seconds at 9V, but not
much longer I bet.
I don't have yet my SGC back (It's coming though), however this requires too much "invasion" on the mainboard so I will wait for a PSU and if its not working then I will start horsing around with it :-)
The damn thing is in very good condition overall and two of the lot of 4 look extremely well almost mint!
